devm_dma_request_chan() to simplify probe
Merge series from Bence Csókás <csokas.bence@prolan.hu>: The probe function of the atmel-quadspi driver got quite convoluted, especially since the addition of SAMA7G5 support, that was forward-ported from an older vendor kernel. To alleivate this - and similar problems in the future - an effort was made to migrate as many functions as possible, to their devm_ managed counterparts. Patch 1/2 adds the new `devm_dma_request_chan()` function. Patch 2/2 then uses this APIs to simplify the probe() function.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
